Abstract

Methods for growing layers of carbon doped GaAs are provided. Methods include exposing a substrate to a gas mixture comprising a source of Ga, a source of As and a dopant comprising a haloalkane under conditions sufficient to grow a layer of carbon doped GaAs on the substrate via hydride vapor phase epitaxy. The haloalkane can include a bromoalkane, a bromochloroalkane, an iodoalkane or combinations thereof. The concentration of carbon in the layer can be 1×10 15 cm −3 or greater.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of growing carbon doped GaAs, the method comprising:
 exposing a substrate to a gas mixture comprising a source of Ga, a source of As and a dopant comprising a haloalkane under conditions sufficient to grow a layer of carbon doped GaAs on the substrate via hydride vapor phase epitaxy, wherein the haloalkane comprises a bromoalkane, a bromochloroalkane, an iodoalkane or combinations thereof   
     
     
         2 . The method of  claim 1 , wherein the haloalkane comprises a bromochloroalkane. 
     
     
         3 . The method of  claim 1 , wherein the haloalkane comprises CBrCl 3 , CBr 2 Cl 2 , CBr 3 Cl, CHBrCl 2 , CHBr 2 Cl, CH 2 BrCl or combinations thereof. 
     
     
         4 . The method of  claim 1 , wherein the haloalkane comprises CBrCl 3 . 
     
     
         5 . The method of  claim 1 , wherein the haloalkane comprises a bromoalkane. 
     
     
         6 . The method of  claim 1 , wherein the haloalkane comprises CBr 4 , CHBr 3 , CH 2 Br 2 , CH 3 Br or combinations thereof. 
     
     
         7 . The method of  claim 1 , wherein the haloalkane comprises an iodoalkane. 
     
     
         8 . The method of  claim 1 , wherein the haloalkane comprises CI 4 , CHI 3 , CH 2 I 2 , CH 3 I or combinations thereof. 
     
     
         9 . The method of  claim 1 , wherein the source of As is AsH 3  or As. 
     
     
         10 . The method of  claim 1 , wherein the concentration of carbon in the layer is about 1×10 15  cm −3  or greater. 
     
     
         11 . The method of  claim 1 , wherein the concentration of carbon in the layer is about 1×10 16  cm −3  or greater. 
     
     
         12 . A method of growing carbon doped GaAs, the method comprising:
 exposing a substrate to a gas mixture comprising a source of Ga, a source of As and a dopant comprising a haloalkane under conditions sufficient to grow a layer of carbon doped GaAs on the substrate via hydride vapor phase epitaxy, wherein the concentration of carbon in the layer is about 1×10 15  cm −3  or greater.   
     
     
         13 . The method of  claim 12 , wherein the concentration of carbon in the layer is about 1×10 16  cm −3  or greater. 
     
     
         14 . The method of  claim 12 , wherein the haloalkane comprises a bromochloroalkane. 
     
     
         15 . The method of  claim 12 , wherein the haloalkane comprises CBrCl 3 , CBr 2 Cl 2 , CBr 3 Cl, CHBrCl 2 , CHBr 2 Cl, CH 2 BrCl or combinations thereof. 
     
     
         16 . The method of  claim 12 , wherein the haloalkane comprises CBrCl 3 . 
     
     
         17 . The method of  claim 12 , wherein the haloalkane comprises a bromoalkane. 
     
     
         18 . The method of  claim 12 , wherein the haloalkane comprises CBr 4 , CHBr 3 , CH 2 Br 2 , CH 3 Br or combinations thereof. 
     
     
         19 . The method of  claim 12 , wherein the haloalkane comprises an iodoalkane. 
     
     
         20 . The method of  claim 12 , wherein the haloalkane comprises CI 4 , CHI 3 , CH 2 I 2 , CH 3 I or combinations thereof.
